Double yellow lines will be painted at Portishead marina next week in a bid to combat inconsiderate motorists and ‘rogue parking’.

The restrictions will be installed in Newfoundland Way and Phoenix Way on a six-month trial in response to concerns over access.

Emergency service vehicles, waste-collection lorries and buses have all struggled to navigate through the estate’s labyrinth of badly-parked cars.

The roadworks will start on Monday, costing North Somerset Council £3,000, with parking wardens and police poised to fine drivers ignoring the restrictions.

Cllr Elfan Ap Rees, the authority’s executive member for highways, believes the alterations will deter illegal parking.

He said: “These roads are narrow and one car parking in an inconsiderate location can cause chaos for larger vehicles.

“By introducing a mix of single and double yellow lines we hope to stop rogue parking and keep traffic flowing around the estate.”
